Still a noob

Okay, so I got this pretty new slave, best one I have so far, I haven't had any exceptional fighters in this game, and you probably won't even consider this one exceptional Record:
69-17-6, but I do because it's the best one I have so far, her name is Shirley and she is a war gladiator. This is her stats*without items and with items*:
81 str 68 intel 71 agility 74 stamina 70 size 73 presence 55 chi
97 str 70 intel 82 agility 76 stamina 72 size 78 presence 64 chi

as far as fight strategy goes, she's really active and blood thirsty, she's level 20 and she just got her weapon skill maxed to 10, now what I can't figure out is what skill to max out next, I want death from above because I love the sound of it, but it says it's for the biggest fighters, and she's not one of the biggest. Looking over the skill tree's, I have absolutely no idea what to decide on, considering devistating power from rage also.
